Set 4 – Lab 6: Diffusion, Osmosis, and Cell Membranes   In the second Osmosis exercise, we looked at how a 20% NaCl solution affects an Elodea spp. leaf. The diagram below is a leaf in a 20% NaCl solution. Fill in the blanks below using the options in bold print to explain the diagrams below: Direction of water movement pertaining to the cell:   into;   out of;   no movement Condition of the cell:   flaccid;   plasmolyzed;   turgid;   lysed Part 1: What is the direction of the water movement in the leaf above? _______________ Part 2: What is the condition of the cells in the leaf above? _______________
